Ring Size Guide: Measurements & Styles

Ring Guide

Discover how to choose the perfect ring, from finding your ideal size and fit to exploring different ring widths, profiles, styles and gemstone settings.

The width of a ring has a significant impact on both its appearance and comfort.

Narrow rings look delicate and elegant, while wider bands create a bolder and more noticeable look. As the band becomes wider, it may feel tighter on your finger. For this reason, it is sometimes more comfortable to choose half or even one size larger for wider rings.

How Do You Know If Your Ring Size Is Correct?

Comfortable fit – Your ring should slide over your knuckle with slight resistance and feel comfortable

Secure on your finger – Your ring should stay in place without spinning excessively or slipping off during everyday movements.

Finger size changes – Heat and activity can cause swelling. Measure relaxed fingers at room temperature for accuracy.

Knuckle size matters – Larger knuckles may need a looser fit, while smaller knuckles may need a closer fit.

Larger gemstones – Heavier centre stones may cause slight rotation, but your ring should still feel secure and comfortable.

Wider bands – Wider rings often feel tighter, so consider choosing half to one size larger for comfort.

Different countries use different ring sizing systems. European ring sizes are based on the inside circumference of the ring measured in millimetres. For example, if your finger measures 58 mm in circumference, your European ring size is 58.

To make choosing the right size easier, we have prepared a conversion chart showing European sizes alongside the most common international sizing systems.

How to Measure Your Ring Size

The easiest and most accurate way to find your ring size is to measure the inside diameter of a ring that already fits you comfortably. Remember that each finger may have a different size, so always measure a ring worn on the intended finger.

Alternatively, you can measure your finger at home using a paper strip, flexible measuring tape, ring sizing belt or ring sizer set. These simple methods will help you determine the right size for a comfortable and secure fit.

Measure Your Finger with a Paper Strip

Cut a narrow strip of paper.
Wrap it around the finger where you plan to wear the ring.
Mark where the paper overlaps.
Measure the length in millimetres – this corresponds to your EU ring size.

Paper measurements may not be exact. If you're between sizes, choose the larger one.
